Tyre press indication

i have a tahoe chevrolet 2007 model, the right hand rear tyre allways read 23 psi, tyre swapped but still, right hand rear tyre still reading 23 psi. what would be the cause and the fix please ?

Was the TPMS reset/retrained when the tire was switched? If not, the procedure is in the Owner’s manual.

plz answer my q?

Likewise, what is the question? Why should it have changed?

By what method are you getting the 23psi reading?
